From Firearms Policy Center:

The District of Columbia’s arbitrary “good reason”/”proper reason” requirement, however, goes far beyond establishing such reasonable restrictions. Rather, for all intents and purposes, this requirement makes it impossible for the overwhelming majority of law-abiding citizens to obtain licenses to carry handguns in public for self-defense, thereby depriving them of their Second Amendment right to bear arms. Accordingly, at this point in the litigation and based on the current record, the Court concludes that Plaintiffs have shown that they are likely to succeed on the merits of their claim that the District of Columbia’s “good reason”/”proper reason” requirement runs afoul of the Second Amendment.
